Electricity

Study electricity without getting zapped! Build your own alternator that can be disassembled and rebuilt again and again with the Transparent Alternator Kit. The Plasma Globe, a small Tesla Coil, produces an alternating high voltage potential which attracts or repels free electrons, making an awesome light show! Snap together electronic blocks to build over 300 different electronic circuits. No wire twisting! When the two electrodes on the Energy Ball are touched simultaneously, the device flashes and makes a warbling sound.
